- Acute urticaria – the most common form, lasting less than six weeks. The trigger is often identifiable, such as an infection, allergy, or medication.
- Chronic urticaria – symptoms persist longer than six weeks, and in many cases the exact cause remains unknown.
- Physical urticaria – triggered by external factors like pressure on the skin, cold or heat exposure, sunlight, scratching, or increased body temperature from exercise or stress.
Common triggers include allergic reactions, viral or bacterial infections, emotional stress, and sensitivity to medications. People with known allergies are more prone to developing hives, but reactions can also occur unexpectedly—sometimes to foods, pollen, environmental substances, or even everyday products you didn’t realize your body reacted to.
Most mild hives clear up on their own and don’t require treatment. However, when symptoms are persistent or severe, doctors may recommend antihistamines, short courses of steroids, or soothing treatments like menthol-based creams to reduce itching and discomfort.
Understanding what triggers your hives—and when to seek medical advice—can make managing the condition far less frustrating.
